This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Total Load = Water + Tank + Substrate + Equipment; PSF = Load ÷ FootprintThe calculation requires: Water Volume (gallons), Empty Tank Weight (lbs), Substrate Weight (lbs), Equipment Weight (lbs), Stand Rated Capacity (lbs). Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.
